VEHICLE WHEEL.

Specification of Letters Patent.

Patented Aug. 1, 11922.

Application 'filed October 3, 1921. Serial No. 504,882.

I of accidental deflation of the tire, so that the automobile may be run a limited distance without changing the tire and without injury to it.

As is well known, pneumatic tires are subject to punctures and blowouts at most inopportune times, and under the present practice when a tire is thus impaired it is necessary to repair it or replace it immediately, since the weight of an automobile on a soft tire will quickly destroy it. By my invention this difficulty is overcome, and the auto;

mobile may be run limited distances on a de:

flated tire'without injury to it, and the tire replaced at a more convenient time.

The manner in which these and other advantages are obtained will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which. I

Figure 1 is a side elevationof an automobile wheel with my invention applied thereto; Fig. 2 is a transverse section through the tire and wheel on the line 2-'2 of Fig. 1 Fig. 3 is a side elevation of the split rim showing rim contracted to receive the auxiliary tread; Fig. 4 is a cross-sectional view of a modified form of the invention;

and Fig. 5 is a face view of the rim shown in Fig. 4.

Referring to the drawings, W represents an automobile wheel, and land 2 the felloe and. felloe band respectively of the wheel. T re resents a pneumatic tire mounted on a split demountable rim 3, the rimbeing fastened on the felloe band by wedges .4 secured onstuds 5 by nuts 6 as well understood in the art. My improvement consists in a band 7 (preferably made of pressed steel) provided with an auxiliary tread 8 projecting outwardly from the band, said band being positioned over the rim 3 and held between the flange 3' of said rim and tire bead by the outward pressure of the tire. The band 7 is placed over the split contracting the rim to a smaller diameter (Fig. 3) and slipping the band over the contracted rim, after which it expands against both tire and band. When the wheels of an automobile are provided with bands 7, and one of the tires becomes deflated, the tread 8 of said band will bear on the ground and support'thc car. Should it be inconvenient to change tires at once (on account of bad weather or limited time) the car may be run on the tread 8 of the band'7 without injury to the tire, as the weight of the car is not on the tire, but on the auxiliary tread. The band 7 is secured to the flange of the rim .rim in the same manner as the tire, i. e., by

3 bymeans of cap screws 9 so that it will not wobble on the rim when the tire T has on the outer edge to keep the tire t in place' Havin described my invention, I claim: A vehlcle wheel provided with a flanged detachable split rim, a pneumatic tire on said rim, and a solid band positioned over the rim between one flange thereof and the tire, the tire being inflated against the band said. band having a tread projecting laterally therefrom and meansfor holding the hand against movement when the tire becomes deflated.

In testimony whereof I hereunto attix my signature.

CHARLES, A. MARIEN.
